INTRODUCTION
High precision, thin film resistors manufactured with a NiCr alloy
spattered onto an alumina substrate. TP resistors
have linear operating temperatures from -55C to +125C. Standard TCRs include
2ppm/C and 5ppm/C. These models
also exhibit excellent long-term stability, low current noise, a low voltage
coefficient and a low thermal EMF. Typical
applications are: Discrete voltage dividers, analogue circuits in industrial
measuring equipment, control, medical
electronics, ATE, aerospace, and reliable power electronics.
